[ale] 2 strange problems have me stumped

[James P. Kinney III]

Thanks for the reply. I may have been a bit unclear. I wrote the fstab
entry, not the mount process for the usb drive. It doesn't seem right
that usb should edit a config file. mtab, yes, fstab, no.

I've got to dig more on how the usb stuff is supposed to work. I do have
a hack around. But a shell script from rc.local that recreates the
deleted entries seems improper.
